Double E proudly presents two models in this series, each catering to different pressure demands:

The Cap King: Expertly designed for operations requiring up to 5,000 psi working pressure, the Cap King is the ideal choice for standard high-pressure environments. It promises reliable containment of well pressure and effective prevention of leaks, ensuring safe and efficient operations.

The Dual Cap King: For more extreme conditions, the Dual Cap King steps up to the challenge with a rating of 10,000 psi. This model is tailored for the most demanding situations, offering enhanced security and robust performance where it matters most.

We understand that one size does not fit all. If our current Cap King models don’t align perfectly with your operational requirements, we’re ready to collaborate and create a custom solution. Whether it’s developing a new Cap King model or modifying an existing one, our team is dedicated to engineering a solution that meets your specific needs.
Choose Double E’s Cap King series for a permanent Oil Saver solution that combines reliability, efficiency, and the flexibility to tailor to your unique well injection or gauge installation needs.
